Alternative implementation idea: pi with a mike feeding audio signals to a detector. If waveform matches Twinkle Little Star (aka sound of rice cooker), send notif("rice is done").
Extensible to other important sounds like smoke alarm, oven timer beeping, and a catch-all that sends notif("weird sound in kitchen, best investigate").
Plugin architecture to allow other contributions for waveforms to recognise different brand gear, eg the beeps from GE being different from Zojirushi.
